Not to mention that the 4870's memory bandwith will be higher than the GTX 260 if its GDDR5 Memory frequencies are high enough and will have overclockable shaders just like the GTX, so the 260 will not be amazingly more powerful.

Both cards should overclock well and though Nvidia has historically provided more headroom, this will be the first batches of the 200 series from Nvidia while ATI has been tinkering with the R600 based architecture for years now.

Hence my comment in the preceding post

Many people here doesn't want or need to justify the cards' prize. They only care about FPS. For them NV is the way to go. Overclock? Then the 4870 will be faster, and the GTX 260 will be faster too, so it will be the same again. And you don't really know how fast are them. You like estimating perfomance of the upcoming cards, but I will tell you again: it's useless. You know NOTHING about how doubling the number of TMUs will affect R600 architecture, and you don't know how and what is improved in the G200 design over G80/G92. Just stop the estimations, wait a few weeks and enjoy the REAL thing

G200 is G80 architecture, RV770 is R600 architecture. Both are old (G80 6 months older actually), so that means nothing.
